That is, after the first stem 11 and the second stem 12 move a predetermined distance upward together, the first stem 11 stops moving, and only the second stem 12 additionally moves a predetermined distance upward. To enable the first stem 11 to move together with the second stem 12 as above, a plurality of elastically supported units 11 a (refer to FIG. 24) which are elastically supported at an outer circumferential surface of the second stem 12 are included at an upper portion of the first stem 11.

The first flower 13 is formed by a plurality of first petals 131 disposed in a circumferential direction, and the second flower 14 is formed by a plurality of second petals 141 disposed in a circumferential direction. Here, the second flower 14 is formed to have a relatively smaller size than the first flower 13 to be accommodated in the first flower 13 while the first flower 13 is closed.

The first petals 131 are rotatably installed at the top portion of the above-mentioned guide member 103. For this, first hinge portions 103 b at which the first petals 131 are rotatably installed are provided at the guide member 103, and second hinge portions 131 a rotatably installed at the first hinge portions 103 b are provided at the lower portion of the first petals 131. In the present embodiment, pins 104 are respectively installed to penetrate the first hinge portions 103 b and the second hinge portions 131 a to enable the first hinge portions 103 b and the second hinge portions 131 a to be rotatably coupled to each other.

To enable the first flower 13 to bloom or be closed by interlocking with the vertical movement of the stems 11 and 12, locking portions 131 b are respectively provided at the first petals 131, and locking grooves 11 c to which the locking portions 131 b are locked are provided at an outer circumferential surface of the first stem 11. In the present embodiment, the locking portions 131 b extend inward from the second hinge portions 131 a. Consequently, when the first stem 11 has moved downward, the locking portions 131 b are locked to the locking grooves 11 c, and the first petals 131 remain closed. As the first stem 11 moves upward, the locking portions 141 b are detached from the locking grooves 11 c and are supported at the outer circumferential surface of the first stem 11, causing the first petals 131 to rotate outward and the first flower 13 to bloom.

The second petals 141 are rotatably installed at the top of the second stem 12. Third hinge portions 12 a at which the second petals 141 are rotatably installed are provided at the top of the second stem 12, and fourth hinge portions 141 a rotatably installed at the third hinge portions 12 a are provided at the lower portion of the second petals 141.

To enable the second petals 141 to rotate with respect to the fourth hinge portions 141 a, a support unit 11 b is formed at the top of the first stem 11. The support unit 11 b selectively supports the lower portion of the second petals 141 in accordance with the relative positions of the first stem 11 and the second stem 12 such that the second petals 141 remain closed. That is, outer surfaces of the second petals 131 are supported by the support unit 11 b and the second petals 141 remain closed when the first stem 11 and the second stem 12 move together, and the outer surfaces of the second petals 141 are spaced apart from the support unit 11 b when only the second stem 12 moves upward, causing the second petals 141 to rotate outward by the self-load.

The driving device 15 includes a driving motor 151 generating a rotary force, and a deceleration unit 152 formed by a plurality of gears 152 a.

The lifting device 16 includes a lifting member 161 rotatably installed at the bottom of the second stem 12, a first lifting guide 162 in which the lifting member 161 is vertically movably installed and connected to the deceleration unit 152 to rotate by the deceleration unit 152, and the second lifting guide 163 formed in a hollow cylindrical shape and having the first lifting guide 162 accommodated therein.

The lifting member 161 is installed at the bottom of the second stem 12 through a screw 164. The screw 164 passes through a through-hole 161 a provided at the center of the lifting member 161 and is coupled to the bottom of the second stem 12. Consequently, the first stem 11 does not rotate even if the lifting member 161 rotates. In addition, the lifting member 161 includes a pair of guide protrusions 161 b protruding outward in a radial direction from both sides of the outer surface thereof and installed at a guide groove 163 a to be described below.

The first lifting guide 162 is connected to the driving device 15 and receives the rotary force from the driving device 15 to rotate. The first lifting guide 162 is formed in the hollow cylindrical shape and the stems 11 and 12 and the lifting member 161 are vertically movably installed therein. A pair of guide slots 162 a vertically extending and guiding the vertical movement of the pair of guide protrusions 161 b are provided at both sides of the first lifting guide 162. Consequently, when the first lifting guide 162 rotates, the lifting member 161 receives force through the guide protrusions 161 b and rotates together with the first lifting guide 162.

The second lifting guide 163 is formed in the hollow cylindrical shape, has the first lifting guide 162 provided therein, and a guide groove 163 a in a spiral shape in which the pair of guide protrusions 161 b are movably installed provided at an inner circumferential surface thereof. Consequently, when the lifting member 161 rotates by the first lifting guide 162, the guide protrusions 161 b provided at the lifting member 161 are guided by the guide groove 163 a, causing the lifting member 161 to move toward one side of an upper side and a lower side. Here, a moving direction of the lifting member 161 is determined by a rotary direction of the first lifting guide 162.

Hereinafter, operations of the indicator 1 configured as above will be described in detail with reference to the drawings.

First, as illustrated in FIG. 19 and FIG. 22, the second petals 141 and the first petals 131 all remain closed when the second stem 12 and the first stem 11 has moved downward.

When the first lifting guide 162 rotates in one direction by the driving device 15 at the above state, the lifting member 161 in the first lifting guide 162 rotates together with the first lifting guide 162. Since the guide protrusions 161 b provided at the lifting member 161 move along the spiral guide groove 163 a, the lifting member 161 moves upward, and accordingly, the second stem 12 moves upward. Since the first stem 11 is supported at the second stem 12 through the elastically supported units 11 a, the first stem 11 moves upward together with the second stem 12.

As the second stem 12 and the first stem 11 move, the locking portions 131 b which have been locked to the locking grooves 11 c are detached from the locking grooves 11 c, and accordingly, the first petals 131 rotate outward with respect to the pins 104. Consequently, as illustrated in FIG. 20 and FIG. 23, the first flower 13 blooms.

Then, the second stem 12 and the first stem 11 move upward, and the first stem 11 stops moving after the second stem 12 and the first stem 11 has moved a set distance. Even after the first stem 11 has stopped moving, the second stem 12 moves by the lifting member 161. As only the second stem 12 moves, the support unit 11 b that has been supporting the lower portion of the first petals 131 is spaced apart from the second petals 141. Consequently, as illustrated in FIG. 21 and FIG. 24, the second petals 141 rotate outward with respect to the fourth hinge portions 141 a by the self-load, causing the second flower 14 to bloom.

In other words, as described above, as the stems 11 and 12 move upward, the first flower 13 and the second flower 14 bloom in order.

In addition, when the first lifting guide 162 moves in the opposite direction by the driving device while the second flower 14 and the first flower 13 are unfolded as above, the stems 11 and 12 move downward, and accordingly, the second flower 14 and the first flower 13 are closed in order.

The indicator 1 may be operated by interlocking with various types of conditions such as an indoor temperature or a humidity level. That is, after setting an optimum condition value, the stems 11 and 12 may move upward as a condition becomes closer to the optimum condition value to enable the first flower 13 and the second flower 14 to bloom, and the stems 11 and 12 may move downward as the condition becomes farther from the optimum condition value to enable the first flower 13 and the second flower 14 to be closed.

For the above-mentioned condition values such as a temperature and a humidity level, the indicator 1 may include a sensor for measuring the condition values such as the temperature and the humidity level, or condition values measured by a separate device may be transmitted to the indicator 1.

In addition, the indicator 1 may be used alone as suggested in the above embodiment, or used by being included in various types of devices such as a humidifier or an air conditioner.

Hereinafter, an indicator according to a second embodiment of the present disclosure will be described in detail with reference to the drawings.

In the present embodiment, as illustrated in FIG. 27 and FIG. 28, an indicator 2 is applied to a water storage unit 3 used in a humidifier, and the like, and is able to display a water level of water filled in the water storage unit 3.

The water storage unit 3 includes a water bottle 31 of which a top surface is open to fill water therein, and a water bottle cover 32 covering the top surface of the water bottle 31.

The indicator 2 includes a stem 21 vertically movably installed at the water bottle cover 32, a flower 22 installed at the top of the stem 21, and a buoyant body 23 installed at the bottom of the stem 21. In the present embodiment, as illustrated in FIG. 29, the five indicators 2 include five stems 21 disposed apart from each other in a circumferential direction, five flowers 22 respectively installed at tops of the five stems 21, and five buoyant bodies 23 respectively installed at bottoms of the stems 21.

The water bottle cover 32 includes five guide units 321 for guiding the vertical movement of the stems 21, and support units 322 supporting first petals 221 to be described below to enable the first petals 221 to be closed.

As illustrated in FIG. 30 and FIG. 31, the guide units 321 vertically extend and guide holes 321 a in which the stems 21 are movably installed are provided at the guide units 321. In the present embodiment, lengths of the stems 21 and lengths of the guide units 321 are formed to be shorter in stages while progressing in the circumferential direction as illustrated in FIG. 29. This is to enable the five indicators 2 to rise in order one at a time in accordance with the water level, such that the flowers 22 of the indicators 2 bloom or are closed one at a time.

Again, referring to FIG. 30 and FIG. 31, the lengths of the guide units 321 are formed relatively shorter than those of the stems 21 to guide the vertical movement of the stems 21, and the lengths of the guide units 321 are formed to be shorter in stages while progressing in the circumferential direction. The length differences between the guide units 321 and the stems 21 installed at the guide units 321 are formed to be equal to the length differences between other guide units 321 and the stems 21. This is to enable the flowers 22 to bloom at equal heights.

The support units 322 extend upward from the top surface of the water bottle cover 32, and are formed in a ring shape with respect to the guide units 321, such that, as the stems 21 move downward, the support units 322 support outer surfaces of the first petals 221 to be described below to enable the first petals 221 to be closed.

The stems 21 include stem portions 211 movably installed at the guide holes 321 a, step portions 212 extending from the tops of the stem portions 211 in the radial direction, and pistil portions 213 extending upward from the step portions 212.

The flowers 22 are formed by the plurality of first petals 221 disposed in the circumferential direction, and second petals 222 disposed in the circumferential direction and formed to have relatively smaller sizes than the first petals 221 to be accommodated in the first petals 221. The first petals 221 include second hinge portions 221 a rotatably installed at first hinge portions 212 a provided at the above-mentioned step portions 212, and the second petals 222 include fourth hinge portions 222 a rotatably installed at third hinge portions 213 a provided at the above-mentioned pistil portions 213. In addition, the second petals 222 include interlocking protrusions 222 b formed on outer surfaces thereof and enabling the second petals 222 to rotate by interlocking with the rotations of the first petals 221.

The buoyant bodies 23 are formed in a shape of a sealed container in which air is filled to float on the water and are installed at the bottoms of the stems 21.

Consequently, as water is filled in the water bottle 31 and the water level rises, the stems 21 move upward in order by a buoyant force acting on the buoyant bodies 23 installed at the bottoms of the stems 21, and the flowers 22 installed at the tops of the stems also move upward. When the outer surfaces of the first petals 221 are spaced apart from the support units 322 as the flowers 22 move upward, the first petals 221 rotate outward with respect to the first hinge portions 212 a by the self-load, and the second petals 222 that have been supported at the first petals 221 through the interlocking protrusions 222 b also rotate outward by the self-load. Consequently, the flowers 22 bloom in order as shown in FIG. 32 and FIG. 33.

In addition, as the water in the water bottle 31 is used and the water level lowers, the stems 21 move downward in order, and the flowers 22 installed at the tops of the stems 21 also move downward. When the flowers 22 move downward, the first petals 221 rotate inward since the outer surfaces of the first petals 221 are supported by the support units 322, and the second petals 222 receive a force from the first petals 221 through the interlocking protrusions 222 b and rotate inward. Consequently, the flowers 22 are closed in order.

Since a number of bloomed flowers 22 change in accordance with the water level in the water bottle 31 as above, the water level in the water bottle 31 may be checked by the number of bloomed flowers 22.

In the present embodiment, although the indicators 2 include the buoyant bodies 23 and vertically move by the buoyant force acting on the buoyant bodies 23, embodiments are not limited thereto, and the indicators may include a separate driving device such as a driving motor and vertically move by the power generated in the driving device.

In addition, although the indicators are formed including stems and flowers in the above embodiments, embodiments are not limited thereto.

As illustrated in FIG. 34, an indicator 4 according to a third embodiment of the present disclosure may include boughs 44 instead of flowers.

In the present embodiment, the indicator 4 includes a flowerpot 41, a plurality of stems 42 vertically disposed on the flowerpot 41 in order, and a plurality of joints 43 disposed between the stems 42 to enable the stems 42 to be rotatably coupled to each other, wherein the stems 42 include the boughs 44 branched out and extending from the stems 42.

The stems 42 and the boughs 44 are formed of light guiding members of a transparent or semi-transparent material to guide light, and a light source (not shown) such as a light-emitting diode is included in the joints 43 to supply light to the stems 42 and the boughs 44.

Consequently, by supplying the light though the light source from the stem 42 positioned at a lower side to the stem 42 positioned at an upper side in order as a condition value transmitted to the indicator 4 becomes closer to the optimum condition value, an effect similar to growing of a plant may be shown. In addition, by blocking the light though the light source from the stem 42 positioned at the upper side to the stem 42 positioned at the lower side in order as the condition value transmitted to the indicator 4 becomes farther from the optimum condition value, an effect similar to withering of the plant may be shown.

In the present embodiment, although the light source is disposed at the joints 43 to supply the light to the stems 42 and the boughs 44 connected to the stems 42 at the same time, this is merely an example, and separately supplying the light to the boughs is also possible. In addition, although not shown, flowers may be disposed at the boughs and the light may be supplied to the flowers in order as the transmitted condition value becomes closer to the optimum condition value, thereby displaying conditions such as a humidity level or a temperature.
